Dear Homeyji,
Title itself is strong enough to entice readers to click on this thread, and beginning of the story is strong enough to hook readers to read more. Overall composition is so nice that one who loves to read this sort of fiction won't lose his/her concentration without reading whole body, that's what I did.
But after reading entire text, I got baffled.
Why does the author think that Roshan (main character of the story) is a cheater? I'm not convinced with title. Sorry to say this but your story does not have any strong reason to call him cheater. Do you mean the main character "Roshan" is cheating with his wife "Sangita" or his ex beloved "Prerna" or himself?
I'm sorry I can't suggest you any optional title as I think its an author's responsibility to label his writing with suitable one.
BTW, I like this story. Good one :)
